WASHINGTON – The National Security Agency has been extensively involved in the U.S. government’s targeted killing program, collaborating closely with the CIA in the use of drone strikes against terrorists abroad, The Washington Post reported after a review of documents provided by former NSA systems analyst Edward Snowden.
In one instance, an email sent by the wife of an Osama bin Laden associate contained clues as to her husband’s whereabouts and led to a CIA drone strike that killed him in Pakistan in October 2012, the Post reported in its online edition Wednesday night.
While citing documents provided by Snowden – the American is hiding out in Russia after being granted asylum there – the Post reported that it was withholding many details about the drone-strike missions at the request of U.S. intelligence officials. They cited potential damage to ongoing operations and national security for their request, the paper reported.
The documents make clear that the CIA-operated drone campaign relies heavily on the NSA’s ability to vacuum up enormous quantities of email, phone calls and other fragments of signals intelligence, or SIGINT, the newspaper said.
The NSA created a secret unit known as the Counter-Terrorism Mission Aligned Cell, or CT MAC, to concentrate the agency’s vast resources on hard-to-find terrorism targets, the Post reported.
The documents provided by Snowden don’t explain how the bin Laden associate’s email was obtained or whether it was obtained through the controversial NSA programs recently made public, including its metadata collection of numbers dialed by nearly every person in the United States.
Instead, the Post said its review of the documents indicates that the agency depends heavily on highly targeted network penetrations to gather information that wouldn’t otherwise be trapped in surveillance nets that the NSA has set at key Internet gateways.
